Alright, I find optics very interesting, lasers being one of my favourite fields of it. So I've searched here for a beginners guide on lasers, I currently have a 5mW true green laser from DX and it isn't serving so well. I am aware of all the safety precautions and will make it my first on my list to cover. So I'm planning on spending around $50 for a complete set including goggles. What do you recommend I purchase? Building a laser for me would be out of the options as I do not have a soldering pencil even though I'm experienced with it.
